Two horses start trotting towards each other, one from A to B and another from B to A. They cross each other after one hour and the first horse reaches B, 5/6 hour before the second horse reaches A. If the distance between A and B is 50 km. what is the speed of the slower horse?
Correct Answer: 20 km\/h
If the speed of the faster horse be fs and that of slower horse be ss then
fs+ss=501=50
and 50ss-50fs=56
Now, you can go through options.
The speed of slower horse is 20km/h
Since, 20+30=50
and 5020-5030=56
